Richard I of England officially invested as Duke of Normandy.
In the Middle Ages, the duke of Normandy was the ruler of the Duchy of Normandy in north-western France. The duchy arose out of a grant of land to the Viking leader Rollo by the French king Charles III in 911. In 924 and again in 933, Normandy was expanded by royal grant. Rollo's male-line descendants continued to rule it until 1135. In 1202 the French king Philip II declared Normandy a forfeited fief and by 1204 his army had conquered it. It remained a French royal province thereafter, still called the Duchy of Normandy, but only occasionally granted to a duke of the royal house as an apanage.
Despite both the 13th century loss of mainland Normandy, and the extinction of the duchy itself in modern-day, republican France, in the Channel Islands the monarch of the United Kingdom is regardless still referred to by the title "Duke of Normandy". This is the title used whether the monarch is a king or a queen.
Richard I (8 September 1157 – 6 April 1199) was King of England from 1189 until his death in 1199. He also ruled as Duke of Normandy, Aquitaine and Gascony, Lord of Cyprus, and Count of Poitiers, Anjou, Maine, and Nantes, and was overlord of Brittany at various times during the same period. He was the third of five sons of King Henry II of England and Eleanor of Aquitaine and seemed unlikely to become king, but all his brothers except the youngest, John, predeceased their father. Richard is known as Richard Cœur de Lion (Norman French: Le quor de lion) or Richard the Lionheart because of his reputation as a great military leader and warrior. The troubadour Bertran de Born also called him Richard Oc-e-Non (Occitan for Yes and No), possibly from a reputation for terseness.By the age of 16, Richard had taken command of his own army, putting down rebellions in Poitou against his father. Richard was an important Christian commander during the Third Crusade, leading the campaign after the departure of Philip II of France and achieving considerable victories against his Muslim counterpart, Saladin, although he finalised a peace treaty and ended the campaign without retaking Jerusalem.Richard probably spoke both French and Occitan. He was born in England, where he spent his childhood; before becoming king, however, he lived most of his adult life in the Duchy of Aquitaine, in the southwest of France. Following his accession, he spent very little time, perhaps as little as six months, in England. Most of his life as king was spent on Crusade, in captivity, or actively defending his lands in France. Rather than regarding his kingdom as a responsibility requiring his presence as ruler, he has been perceived as preferring to use it merely as a source of revenue to support his armies. Nevertheless, he was seen as a pious hero by his subjects. He remains one of the few kings of England remembered more commonly by his epithet than his regnal number, and is an enduring iconic figure both in England and in France.
